Chromalox MWSS offers internal stainless steel construction and is engineered to operate at 300˚F (150˚C). The MWSS Series is designed for high purity applications like deionized, demineralized or distilled water. The stainless steel construction provides superior corrosion protection. Its electric heating core assures responsive and precise temperature control in a space saving package. The system is suitable for a large range of heating needs with a compact design. The MWSS operates in a closed loop system using a cold expansion tank (optional).


Chromalox MWSS system is great for applications such as reactors, evaporators, dryers, platen presses, heat exchangers, roll heating, or any jacketed kettles / vessels / tanks.

Hot water systems can be used in a variety of industries such as chemical, plastics, cosmetics, automotive, rubber, refining, pharmaceutical, non-woven / textiles/ fibers, aerospace, or any other industrial market.


Chromalox MWSS systems are ruggedly constructed for industrial applications. The heavy-duty, steel support base features channel grooves for forklift transport. The heater chamber is fully welded and houses Chromalox brand, long-lasting heating elements. The panel is fully UL-listed and assembled in-house. The pump is air-cooled with a mechanical seal, rated to 300˚F (150˚C). The final assembly is fully-shop tested prior to shipment.
